' FAN SUPPORT.

Application filed .Tune 19, 1925. Serial No. 38,376.

` hereinafter specifically referred to, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings:

Figure 1' is a side elevation of the fan support constucted in accordance with my invention.

Figure 2 is a longitudinal sectional view of the same. l Y

Figure 3 is a top plan view showing the various adjustments of the device7 and Figure 4 is a plan view of the device in normal position and,

Figure 5 is a view partly in section and partly in elevation showing the adjusting means for the device.

Figure 6 is a detail view of the adjusting plate.

several views, the numeral 5 designates a vertically arrangedarm adjustable axially about the pin 6, the usual adjusting screw 7 being Vprovided for coaction with a lug 8 at the lower end of the arm for accomplishing this axial adjustment. As shown in Figure 2 the upper end of the arm 5 is formed with a horizontally extending sleeve or bearing 10 having one end substantially conveX as at 11. A threaded rod 12 extends through this sleeve or bearing 10 and ter- It has been foundfrom experience thaty inmates at one end in a bearing 13 which extends at right angles to the bearing or sleeve 10. A pulley shaft 14 is journaled in this bearing and carries the usual pulley 15 with which the usual band belt is engaged. Arranged on the threaded rod 12 adjacent one end thereof is a cup shaped washer 16 while a nut 17 is threaded on this end of the rod and is formed with a surface 18 received in the concaved washer 16. This nut 17 is provided with a pair of slots 19A through 1vhich a locking pin 20 is'passed, the latter passing through openings 22 in the rod.

As shown in Figures 4 and 5, the opposite end of the bearing or sleeve 10 is flared andv is provided with teeth or serrations 23. An adjusting plate 24 is received on this end of the rod' and is shaped-to correspond to the iiared end of the sleeve or bearing 10 and is also provided with serrations'25 for Vengagement with the serrations 23. A lock nut 26 is arranged on this end of the .rod and .is provided with the slot 27 for the reception of the locking key or pin 28.

Y Extending laterally from the rod 12 intermediate its ends is a pin or lug 29 which is accommodated in a diagonal slot 30 in the sleeve or bearing pin.

Vhen it is desired to adjust the device the nuts 17 or 26 are loosened and the'rod 12 slid longitudinally to the desired posi# tion. In order to compensate for wear of the bore of the sleeve or bearin 10, the locking yplate 24 is disengaged rom the flared end of the sleeve and the sleeve is then arranged in the correct position and then locked by means of the plate and lock nut 26. It will also be obvious that in adjusting the rod l2 longitudinally the same will be adjusted gradually to position the bearing 12in alinement with the belt, not shown.

Vhile I have shown and described the preferred embodiment of the invention, I desire to have it understood that such changes may bemade in the form, construction and arrangement of parts andoperations7 as will not depart from thespirit of the invention or the scope of the subjoined claim.

What is claimed is:

A device of the character described comprising an arm, a bearing carried thereby and provided with a slot, a rod passing through the bearing and having its opposite ends threaded, a lug on the rod and engaged in the slot, means for Supportingr a pulley at one end of the rod, one end of the bearing being` flared and provided with serrzv tions, a looking plate on the rod and also having serrations and engageable with' the lirst mentioned Serrations and look nuts on the opposite ends of the rod and one oi which is engageable with the serrated looking member and adapted to lock the beati-iv 10 ing` in lateral or adjusted position.

In testimony whereof I nlx my signature.
